***********SOLD**********************************
Dinan muffler welded to the factory cat-back exhaust is for sale. It is a complete bolt in piece. I hate to ask this much, but the muffler alone sells for $799 new, without the resonator and cat-back piping. $300 shipped anywhere in the lower 48. Pics here:

Dinan's Free Flow Exhaust for the 3 series models provides increased flow for power gains without the excessive noise associated with typical "performance" mufflers. The Dinan exhausts feature rigid and durable muffler cases, manufactured from 20 gauge 304-stainless steel for optimum corrosion resistance. Internally, the systems feature Dinan's Tuned Resonance Chamber technology which provides the optimum balance between maximum power gains and a civilized, yet sporty exhaust note. The Dinan exhaust also provides substantial weight reduction. The aggressive polished stainless steel exhaust tip gives the cars a tasteful performance look as well.
